Improve idlharness-ShadowRealm integration
By exposing a fetch_spec() on globalThis in testharness-shadowrealm-inner,
we no longer need to have IDL tests in separate files for ShadowRealm, as
the regular idlharness.js will just run there.
Delete all existing idlharness-shadowrealm.window.js files and incorporate
them into their neighbouring idlharness.any.js files.
It seems sufficient to run the IDL tests only in shadowrealm-in-window;
repeating them in every ShadowRealm scope seems like overkill.

Improve test message in idlharness
This gets me every time. If we are testing that an interface is not
exposed, we should be clear about that in the test message.

Don't test namespaces in idlharness if not exposed
Instead, if a namespace is not exposed, test that there is no global
property of that name, similar to what we do with interfaces.
